My plan with the slice seeder was to put it down at a rate of 5 pounds per thousand going two ways to give me 10 pounds per thousand so I just went across the lawn one way with the seeder then broadcasted about half the seed then came across at a right angle to my first pass and broadcasted more seed its tough to see in this picture but you can kind of see the grooves. As far as seed I found a local seed supply house and after talking with the owner there for a while I went with their overseed mix which is 70% percent PRG I believe Top Gun II, Accent II and Revenge GLX and then 30% KBG can't remember the exact name, he felt this was best because with the ryegrass quick germination it will have the best chance at getting established before the summer heat and hopefully some bluegrass will fill in but I can always oversees with bluegrass in the fall. Thanks for all your help guys and I will keep you updated as it starts to fill in!
